| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed spectrum-folding scalar feedback (SF-SFB) architecture with a narrowband feedback circuit for wideband digital predistortion (DPD). In this paper, the required condition of SF-SFB DPD signal processing is analyzed. Simulation and experiment are conducted to verify its performance with long term evolution (LTE) signal. The results show that it has compensation accuracy same as the conventional DPD regarding error vector magnitude (EVM) and adjacent channel leakage power ratio (ACLR). It has validated that SF-SFB DPD has sufficient nonlinear compensation performance for 5CC-LTE signal with 100 MHz RF bandwidth. | |
